GOLD-SEPARATOR.

Application filed June 15, 1908.

To all whom it may concern:

Be it known that I, LEVAN L. L. SwnNsoN, a citizen of the United States,residing at Longmont, in the county of Boulder and State of Colorado,have invented new and useful Improvements in Gold-Separators, of whichthe following is a specification.

My invention pertains to means for separating gold from gold-bearingsand and other substance; and it has for its object to provide a simpleand inexpensive apparatus through the medium of which sand and the likemay be efficiently robbed of the gold present therein, and this with buta minimum amount of attention on the part of the attendant of theapparatus.

The invention will be fully understood from the following descriptionand claim when the same are read in connection with the drawings,accompanying and forming part of this specification, in which:

Figure 1 is a vertical section of the apparatus constituting the bestpractical embodiment of my invention known to me. Fig. 2 is a horizontalsection taken in the plane indicated by the line 2-2 of Fig. 1, lookingdownward.

Similar letters designate corresponding parts in both views of thedrawings, referring-to which:

A is the receptacle of my novel apparatus which is preferably ofglobular form, and is provided at opposite points with projections (1,preferably trunnions, through the medium of which it is supported in asuitable frame A and this in such manner that it may be oscillated, whendeemed expedient, to increase the efliciency of the a paratus. On thebottom of the said rece tac e A is arranged a fixed deflector b, anc inthe top of the receptacle is formed an opening 0 surrounded by ahorizontally disposed flange d.

C is an agent, preferably mercury or quicksilver, which is arranged inthe rece tacle A to about the height illustrated, anc has for its officeto permit water, and sand or other gold-bearing substance to assupwardly through it, and to take up gol d and separate the same from thesand and water incidental to such passage.

D is a flanged cover platewhich is detachably secured, by bolts orotherwise, to the receptacle flange d, and is provided with a centralopening e and with a plurality of comparatively small openings f,grouped about the said central opening 6. The open- Specification ofLetters Patent.

Serial No. 488,567.

ing e is designed to receive and hold in an upright position a pipe Ewhich extends down in the receptac e A to a point adjacent to the bottomthereof and is there provided with an annular cap F. This cap F issuitably secured on the lower end of the pipe E and is designed tosurround and be sepa rated by an intervening space from the beforementioned conical deflector I). Said cap F is also designed to bear atits edge on the bottomof the receptacle A, and is provided with aplurality of apertures g for a purpose herein set forth. At a pointabove the receptacle A the pipe E is connected by a coupling G with apipe or other suitable conduit H, which latter is designed to lead froma source of water and gold-bearing sand supply.

In the practical use of my novel apparatus, the water and gold-bearingsand pass downward through the pipe E and bring upward against thedeflector b, after which the water and sand. pass upward, as indicatedby arrows, through the mercury or quicksilver C. The gold commingledwith the sand is, however, taken up by the said mercury or quick silver,with the result that the water and sand alone pass out of the receptacleA through the openingsf provided in the cover plate D.

It will be readily understood from the foregoing that when the water andsand are turned outward and upward by the conical deflector b, theminute apertures g in the cap F will distribute the water and sandthroughout the mercury or quicksilver C, and in this way the thoroughseparation of the gold from the sand will be accelerated. The space inthe receptacle A above the body of mercury or q uicksilver O is providedin order to enable said body to rise with the water and sand, and thislatter also contributes to the efficiency of the apparatus in separatingthe gold from the sand.

When it is desired to discharge the commingled gold and mercury orquicksilver from the receptacle, the same may be readily accomplished bydumping the receptacle after the pipe E is disconnected from the ipe Hand the cover plate 1) is removed from the receptacle.

The apparatus herein illustrated and described constitutes the bestpractical embodiment of my invention of which I am cognizant, but it isobvious that in the future practice of the invention such changes ormodifications may be made as fairlyfall within the scope of my inventionas defined in the claim appended.

It will be gathered from the foregoing that in practicing my inventionthe'water and sand or other gold bearing substance pass down into themercury or quicksilver and up through the same, and incidental to suchpassage the gold is taken in to the mercury.

Having described my invention, what I claim and desire to secure byLetters-Patent, is:

An apparatus for the purpose described, comprising suitable support, areceptacle of globular form having trunnions at 0p osite Joints'ournaled in the su )ort an also 1 l I having a conical deflector on itsbottom and an opening in its top, a cover 1plate detachabl connected tothe receptae e and having a plurality of small 0 enings, a pipeextending down through said. cover plate and having a cap at its lowerend bearing on the bottom of the receptacle, around said deflector, andalso havinga plurality of small apertures in said cap, and a supply pipedetachably connected with. the upper end of the first named pipe.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
